AI voice agent
What an AI voice agent is, what happens inside one during a call, and how it relates to an AI receptionist.
The short answer
What is an AI voice agent?
An AI voice agent is software that holds a spoken phone conversation with a person to get a task done. It listens with speech recognition, decides what to say and do with a language model, and answers in a synthesized voice. Unlike a recorded phone menu, it understands free speech and can act during the call: look up a record, book an appointment, send a text or transfer to a person. It can answer inbound calls or place outbound ones.
How it works
Each turn of the conversation runs through the same loop, fast enough to sound like a normal call:
- 1Speech-to-text turns what the caller just said into text.
- 2A language model works out what the caller wants and picks the next step, following your instructions and your knowledge base.
- 3If the step needs an action, the agent calls a tool: checks a calendar, reads a CRM record, sends an SMS.
- 4Text-to-speech speaks the reply, and the loop starts again.
- 5After the call, the recording, transcript and summary are saved.
Example
A real-estate agency gets leads from a website form at all hours. An AI voice agent calls each new lead within minutes, asks the screening questions from the agency's script, books a viewing for the ones who qualify, and writes a summary of the call to the lead's record in HubSpot. The agents start the day with booked viewings instead of a list of names to chase.
AI voice agent vs AI receptionist
An AI receptionist is one job an AI voice agent can do: answering a business's inbound calls. Voice agent is the broader term, and it also covers outbound work such as follow-up calls, reminders, lead qualification and calling campaigns. Daber AI agents do both: they answer inbound calls and run outbound calls and campaigns.
Questions
Can an AI voice agent make outbound calls?
Yes. Outbound calls follow a script or call flow: reminders, follow-ups, lead qualification or feedback calls. Rules on automated calls differ by country, especially for sales calls, so check the ones that apply to you before you start a campaign.
What languages can an AI voice agent speak?
It depends on the speech and language models behind it. A Daber AI agent speaks the caller's language, Hebrew and English included. Test it with the names, places and terms your own callers use.
